2020 Annual Management Plan

Snettisham Hatchery

Douglas Island Pink and Chum, Inc.

This Annual Management Plan (AMP) plan is prepared to fulfill the requirements of 5 AAC

40.840. This plan must organize and guide the hatchery’s operations, for each calendar year,

regarding production goals, broodstock development, and harvest management of hatchery

returns. Egg take through release details are included in planning for succeeding calendar

years. Inseason assessments and project alterations by the Douglas Island Pink and Chum (DIPAC)

or Alaska Department of Fish and Game (ADF&G) may result in changes to this AMP in order to

reach or maintain program objectives. DIPAC will notify the ADF&G private nonprofit (PNP)

hatchery program coordinator in a timely manner of any departure from the AMP. The ADF&G

PNP coordinator will advise as to whether an amendment, exception report, or other action is

warranted. No variation or deviation will be implemented until an AMP amendment has been

approved or waived by both the department and DIPAC. This policy applies to all hatchery

operations covered under the AMP.

1.0 Executive Summary

1.1 Introduction

In 1979, the State of Alaska constructed Snettisham Hatchery (SNT). The hatchery was originally

intended to produce chum, Chinook, and coho salmon for common property fisheries. In 1988, the

State of Alaska began a sockeye salmon program. As the sockeye salmon program grew, other

production was discontinued or moved to other locations. In 1996, DIPAC was issued PNP

hatchery permit #39 for SNT. DIPAC operates SNT exclusively as a sockeye salmon facility. The

sockeye salmon production at SNT can be broken into two categories: A) Alaska Production –

sockeye salmon reared for release at the hatchery, as well as supporting several lake-stocking

programs in Southeast Alaska, and B) Transboundary River (TBR) Production – incubate and

thermal mark eggs for several TBR drainages in British Columbia. Alaska production falls under

standard hatchery protocols and is addressed in Section A of this management plan. TBR

production is part of the Pacific Salmon Treaty; details such as permitted capacity, egg take goals,

egg take guidelines, and stocking locations fall under review by the Pacific Salmon Commission

(PSC) and are subject to change. TBR production information can be found in Section B of this

plan and should be considered “for informational purposes only.”

1.2 New This Year (production, harvest management, culture techniques, etc.)

In response to the Covid-19 pandemic, DIPAC is taking measures to reduce seasonal staffing

needs at all of its facilities. With this goal in mind, all marked groups of BY18 smolt will be

combined and released via the “Direct Saltwater” release strategy. No new programs or further

amendments are anticipated at this time.

1.5 Production Summary

Snettisham Hatchery has six incubation modules, each capable of incubating 2.5 to 3.0 million

sockeye salmon eggs for lake-stocking programs. There are a total of 12 incubation/rearing modules

that can be utilized for the smolt-rearing program; two large modules provide space for 16 start-tanks

and 10 smaller modules provide an additional 32 start-tanks. Facility capacity is as follows:

King Salmon Lake sockeye salmon 1 250,000

Total 16–18 32,750,000 a Includes 600,000 fry released at Sweetheart Lake

1.6 Current Permitting

The permitted capacity at SNT is 33,500,000 sockeye salmon green eggs for all projects. The

release at SNT is the equivalent of 12.5 million eggs; however, the current operating limit is 9.0

million smolts, which is equivalent to approximately 10.3 million green eggs, assuming low

mortality due to infectious hematopoietic necrosis virus (IHNV). The SNT basic management plan

calls for a review of this egg take limitation to be conducted annually during drafting of the Snettisham

Hatchery Annual Management Plan. Snettisham Hatchery sockeye salmon stock will be used to

stock Sweetheart Lake with up to 600,000 unfed fry. If escapement levels are not reached in Speel

Lake, ADF&G may arrange to have SNT take up to 5.0 million sockeye salmon eggs for back-


3

planting into Speel Lake. Additionally, up to 3.0 million sockeye salmon eggs may be collected

for back-planting into Crescent Lake, if necessary.

Snettisham Hatchery also incubates eggs for a joint fisheries enhancement program between

Canada and the U.S. The maximum number of eggs to be incubated is defined in the Pacific

Salmon Treaty.

Section A: Alaska Production

2.0 Snettisham Hatchery sockeye salmon

2.1 Program details

The egg take goal is 11.8 million sockeye salmon eggs. The egg take goal provides enough eggs to

produce 9 million smolt for release at SNT, 0.6 million fry for Sweetheart Lake stocking, and provides

a contingency amount of eggs to mitigate potential IHNV losses. If actual IHNV losses are less than

the contingent amount, surplus will be discarded to meet release goals. The SNT sockeye salmon

broodstock was developed using Speel Lake stock. Speel Lake is a backup brood source for SNT.

Adult sockeye salmon returns to SNT support common property harvests (including the Sweetheart

Creek personal use fishery), cost recovery harvest, and broodstock for the hatchery. Since 1997,

enough broodstock have returned to the hatchery to meet the egg take goal. It is anticipated the egg

take goal will be reached again this year.

2.3 Broodstock capture method

Returning broodstock are captured in the hatchery fish ladder, graded for quality, sorted by sex, and

held in segregated raceways until fully mature.

2.4 Spawning

Individual fish are dispatched with a blow to the head. Gamete collection, fertilization, water

hardening, and disinfection are done in accordance with ADF&G sockeye salmon culture protocol.

Fertilized eggs are placed in Kitoi boxes. Emergent fry volitionally emigrate to fry start-tanks to

begin rearing.

2.5 Egg take schedule

Egg takes occur in September through October.

2.6 Carcass disposal

Broodstock carcasses will be collected at the end of each egg take and transported to a minimum

depth of 70 fathoms in Speel Arm for disposal.

2.7 Planned releases this calendar year of previous brood years’ production

In 2020, SNT has designated 549,700 brood year 2019 (BY19) unfed sockeye salmon fry for planting

into Sweetheart Lake. These fish will contribute to commercial fisheries and the Sweetheart Creek

personal use fishery. Target dates for stocking unfed fry into Sweetheart Lake are May 15 to June 15.

In 2020, SNT has designated just under 9.0 million BY18 sockeye salmon smolt for release at the

hatchery. In 2010, a pilot study was initiated using SNT sockeye salmon to evaluate and compare

the marine survival rates of short-term saltwater rearing versus the standard practice of a direct

release from the hatchery. In 2011, the study was expanded to also include direct releases into the

saltwater, as well as transporting smolt to the Port Snettisham entrance by vessel for release. In

2020 the study will be postponed and all smolt release via the direct saltwater release strategy in

order to reduce staffing requirements in response to the Covid-19 pandemic.

3.0 Speel Lake sockeye salmon

3.1 Program details

An adult weir will be installed at Speel Lake to aid in determination of sockeye salmon escapement.

The Speel Lake sockeye salmon escapement goal is 4,000–9,000 adults. Weir counts should be

provided to the Juneau area CF management biologist, or a designee, on at least a weekly basis. A

goal of 800 age-weight-length (AWL) samples will be taken proportionately throughout the run

timing.

If Speel Lake escapement is below 4,000 adults for two consecutive years, DIPAC will consult

with ADF&G about possible enhancement/mitigation projects to increase returns to Speel Lake.

Up to 5 million eggs may be collected at Speel Lake and reared at SNT. No more than 50% of the

escapement to Speel Lake can be used for broodstock. No egg take will occur if escapement is less

than 400 fish. Progeny of the Speel Lake eggs are to be released at Speel Lake or at SNT.

through aerial surveys. Harvest management actions used to protect Speel Lake sockeye salmon

returns also protect Crescent Lake returns. Sockeye salmon eggs may be collected at Crescent Lake

for back planting, if necessary. Limnology studies done by ADF&G indicate zooplankton abundance

may limit sockeye salmon growth, which means back planting smolt or presmolt will have higher

adult returns than planting fry. Crescent Lake stock has been used for fry plants into Sweetheart Lake.

5.0 Harvest Management

5.1 Special harvest area (SHA)

The Speel Arm Special Harvest Area (SHA) is described in regulation 5 AAC 40.032(a)(4) as the

waters of Speel Arm north of 58°03.42′ N. lat. (a point 0.5 nautical miles south of Bogart Point,

Figure 1). The commissioner shall open and close, by emergency order, fishing periods during which

the hatchery permit holder may harvest salmon within the special harvest area.

5.3 Common property fisheries management

5 AAC 33.378. District 11: Port Snettisham Hatchery Management Plan.

(a) The intent of this management plan is to provide basic guidelines for managing enhanced

sockeye salmon production from Port Snettisham.

(b) The department shall manage returns from the Snettisham enhancement program to

ensure in order of priority:

(1) Sustainable production of wild sockeye salmon from Crescent and Speel Lakes.

(2) Management of Snettisham enhanced sockeye salmon returns may not prevent

achieving escapement goals or Pacific Salmon Treaty harvest sharing agreements for Taku

River salmon stocks.

(3) Assessment programs shall be conducted frequently during harvest and annually to

estimate Snettisham wild sockeye salmon stock escapements and contributions of enhanced

sockeye salmon to the District 11 commercial fisheries.

(4) Common property harvests in the SHA shall be conducted by limiting time and area

to protect the wild sockeye salmon runs.

Commercial fisheries

In 2020, ADF&G anticipates taking the following management measures in District 11 during the

fishing season, although inseason assessment of run sizes will dictate which measures are

employed and to what extent. Management of the Stephens Passage area will focus on

conservation of Snettisham wild stock sockeye salmon runs, particularly during July. ADF&G

plans to implement a 6-inch minimum mesh size restriction in Section 11-B south of Circle Point

to limit harvest rates on wild stock sockeye salmon runs, while allowing harvest of hatchery-

produced chum salmon returning to Limestone Inlet. The mesh restriction is expected to be

relaxed in early August. Port Snettisham will remain closed inside a line from Point Anmer to

Point Styleman through late July or early August. Commercial openings inside Port Snettisham

may occur after this time if wild stock escapements are developing adequately.

Commercial openings in the Speel Arm SHA will depend on sockeye salmon escapement into

Speel Lake and DIPAC’s progress toward broodstock goals. Fishery management decisions for

this area will be made jointly by ADF&G and DIPAC.

Personal Use Fishery:

In 2020, a personal use fishery will be allowed in Sweetheart Creek to offer the public an

opportunity to harvest sockeye salmon and to promote a more complete harvest of the limited

returns expected at this site. As a result, the personal use fishery will be open 7 days per week

from June 1 to October 31. The fishery will occur in waters of Sweetheart Creek upstream from

an ADF&G regulatory marker located near the stream mouth.

Sport Fishery:

In 2020, sport fishing for Chinook salmon will be closed in the waters of District 11, Sections 12-

B, 15-B and 15-C from April 15 through June 14. During this closure Chinook salmon may not be

targeted or retained. This will not impact the sport fishery for sockeye salmon. During the rest of

the year sport fisheries will be managed as described in codified regulations for these waters. The

department may use emergency order authority to address issues as they arise in season.

5.4 Cost recovery Harvest Management:

For the 2020 fishing season, DIPAC management has no cost recovery goal for sockeye salmon

returns to SNT. DIPAC’s chum salmon cost recovery is expected to fulfill the budgetary needs of

the SNT smolt program. A limited area in the SHA near the mouth of the Speel River will be

closed to fishing for a portion or all of the season to allow a milling area for wild stock Speel Lake

returns; the boundaries of the area may be modified depending on results of stock identification

sampling. Fish may be harvested 7 days per week after they enter the terminal freshwater area

north of the south end of the airstrip at SNT. The number of harvest days per week in the

remainder of the SHA may be limited to provide for Speel Lake wild stock escapement needs.


10

The hatchery operator harvesting salmon within the SHA is exempt from the provisions of 5 AAC

33.310. Fishing seasons and periods for net gear. Notwithstanding 5 AAC 33.330, all types of

legal gear may be used for this activity.

6.0 Additional Information

6.1 Donor Stock Management

Port Snettisham Sockeye Salmon

Returning Snettisham sockeye salmon will be harvested by drift gillnet gear in Section 11-B. With

the exception of the Speel Arm SHA, Port Snettisham is expected to remain closed during the

month of July and portions of Port Snettisham may remain closed into August to protect wild

stock sockeye salmon returning to Speel and Crescent Lakes. Common property fishery openings

in Port Snettisham may occur after this time if wild stock escapements are developing adequately.

Common property openings inside the Speel Arm SHA may occur if a surplus to DIPAC’s cost

recovery and broodstock requirements of hatchery-produced sockeye salmon is identified and

wild stock escapements are developing adequately; fishery management decisions for the Speel

Arm SHA will be made jointly by the ADF&G and DIPAC.

6.2 Marking objectives

All sockeye salmon will be otolith marked. Hatchery water temperatures are manipulated to create

mark patterns on the otoliths of the fish to aid in assessment of project success, management of

enhanced returns, and compilation of harvest-sharing performance. Each sockeye salmon release

group will have a different mark (except as noted above) for future identification and discrimination

from natural stocks. Determination of otolith mark patterns is made each year by the ADF&G otolith

lab, through consultation with a small group including representatives of the lab, DIPAC, and

department biologists. A well-defined and identifiable otolith mark is critical to evaluation of various

programs, and the otolith lab supervisor will define the marking parameters (e.g., temperature change,

cycle times, time of initiation of mark, etc.). Every reasonable effort will be made to accommodate

concerns of the hatchery operator.

Mark-recovery programs are operated to provide contribution estimates by release group in Districts

6, 8, and 11 drift gillnet fisheries, Canadian in-river fisheries on the Taku and Stikine Rivers, and cost

recovery fisheries in Port Snettisham. Sampling of sockeye salmon spawners is also conducted at fry

plant locations and nearby sites to assess contribution of release groups to escapements. Sample sizes

for mark–recovery efforts are determined through consultation with ADF&G otolith lab staff, fishery

managers, stock assessment biologists, and hatchery staff. Such data allows hatchery managers to

assess the success and harvest contributions of their program and provides information to managers

on effects of management actions and contributions of wild stocks and hatchery stocks, which is

important for comparison with historical data for management of wild stocks.

transboundary Stikine and Taku rivers. The TTC reviews all aspects of the King Salmon Lake

project. A TEPP is prepared annually by the TTC and approved by the Transboundary Panel (Table

11). King Salmon Lake is an approved egg source for a fry back-planting program in King Salmon

Lake. Canada conducts egg takes and transports fertilized eggs to SNT, where the eggs are

incubated over the winter months. Hatchery water temperatures are manipulated to create mark

patterns on the otoliths of the fish to aid in assessment of project success, management of enhanced

returns, and compilation of harvest-sharing performance. The fry are to be transported to King

Salmon Lake and released. Canada conducts studies of freshwater survival, smolt outmigration,

and monitors zooplankton populations and limnological conditions in the lakes.
